A slotted metallic tube, D, is soldered or otherwise connected to this extension O', and guides a notched bolt or rack, D', which slides forward and backward in tube D by pressing on its button or knob a, and is re-v tained in position by spring-pawl E. The end of bolt D acts on that leg of band-spring applied to band B, and forces the latter forward or backward, as required, according as bolt Dy is pushed forward or spring-pawl E released from the notches.

For the purpose of simplifying and lightening this construction, I obtain the same effect on band B by introducing a wedgeshaped piece, F, of cork or other material, between the legs ofthe band-sprin g O', which wedge is pushed up or down as it is desired to make the hat larger or smaller.
